Superliga

Season

Format:
28 teams, each plays the others once.
Additionally each team plays one more game in a round of traditional derbies (clásicos) - with hosting reversed compared to the first meeting between the two - for a total of 28 games each, over 28 game weeks.

Scoring points:
3 points for a win, 1 point for a draw, 0 points for a loss.

Relegation from the league:
Each team's points from participation in the 2015, 2016, 2016/2017 and 2017/2018 Primera División are summed, and that total is divided by the number of games played during that period (a total of 30, 46, 76 or 104 games).
Teams are ranked in a Promedio table, based on the resulting average score.
25-28 place in the Promedio table: relegated to Prim B Nacional
